Ads keep popping up in a new tab the first time I click on any link. They only pop up on the first time I click them every few minutes, however. I've noticed that the U.R.L. for the new tab mostly says "hitcpm.com", at least until it redirects.

I've read that filters guide a bunch of times, but it never clicked with me that you could use $popup. Is the equal sign part of what is being filtered (i.e., anything that contains "/watch?key=" without the quotation marks), or is it some other sort of operator?

Thanks for your time, I'm sure that this will help me a ton (as well as others).

Now I'm having an issue where every time that I right-click on a source, because I like to open the sources in a new tab (because I often need to try multiple sources), it just opens the source as if I've left-clicked on it instead. I don't see any redirect URL or anything.
